Effect of Mechanical and Chemical Treatments on Seed Germination in Pongamia glabra L.
13 / 8
Keywords:
Pongamia glabra, mechanical treatment, chemical treatment, seed germination.Abstract
Seeds of Pongamia glabra, a medicinally important ornamental tree were subjected to various types of treatments for enhancing seed ge germination. Mechanical treatments enhanced seed germination upto 85%. On the other hand, treatments with H,SO, and HCI also enhanced seed germination and the seeds treated with concentra ted HCl just for a minute showed 91.3% germination, while seeds treated with hot water (50°C) exhibited highest germination (98%). Scarified seeds kept at 25°C showed 82% germination, while seeds sown at the depth of 3 cm exhibited 86% germination.
